If I wanted to use the Hy-Tower on 160m at 1500 w p.e.p. there could be two alternative choices:
1) I would just leave off that coil and add a top section as a capacity hat to increase the effective length of the radiator to where it can reach 2 Mega-sickles. You could experiment with a horizontal wire or two run off the top horizontally if you have a little room. I would start with one 50 foot wire or two 25 foot wires. Almost any angle would be fine. 2) You could easily shunt feed the tower. I have done that with a 60 foot tall Rohn 25G Tower and it worked extremely well for me. Towers and Florida weather don't mix well, so I don't do that kind of thing now! Just use a big variable cap to set up your shunt feed. I love that scheme. It would still give your antenna a very small footprint and let you run QRO. > It seems this was discussed a while back, but I need some updated info.
